Can you keep Pea Puffer and Swordtail together?
Algorithmically generated environmental and behavioral compatibility report.
Algorithmic Assessment
Aggression incompatibility. Pea Puffer is an aggressive/territorial species. Peaceful or community fish like Swordtail cannot be housed with highly territorial fish safely.
Scientific Parameter Comparison
Cross-reference water chemistry, temperature range envelopes, and physical dimensions of Pea Puffer and Swordtail.

⚠ Physiological Mismatch Report
Our stocking engine calculations indicate that putting these two species in the same tank causes acute physiological strain. Below are the calculated parameters that violate safe cohabitation ranges:
⚔️ Do Pea Puffer and Swordtail Fight?
Behavioral analysis indicates a severe compatibility clash. The Pea Puffer is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Swordtail, making them completely incompatible cohabitants.
🍽️ Swimming Layers & Feeding Competition
To satisfy their dietary requirements, offer a varied feeding schedule. Sinking pellets or wafers are ideal for bottom dwellers, while floating flakes or micro-granules support mid and top dwellers. The Pea Puffer occupies the mid layer, while the Swordtail occupies the top layer. This separation of swimming zones naturally minimizes direct interactions and reduces competition during feeding times.
📏 Size Difference & Predation Threat
A major physical size discrepancy exists between these two species. The Swordtail grows to 4.5 inches, which is over 5 times larger than the Pea Puffer at only 1.0 inches. There is a high risk of predation, as predatory fish will naturally consume any tank mate that can fit into their mouths.

Frequently Asked Questions: Pea Puffer & Swordtail Compatibility
Are Pea Puffer and Swordtail good tank mates?
Aggression incompatibility. Pea Puffer is an aggressive/territorial species. Peaceful or community fish like Swordtail cannot be housed with highly territorial fish safely.
Can you put Pea Puffer and Swordtail in the same tank together?
Behavioral analysis indicates a severe compatibility clash. The Pea Puffer is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Swordtail, making them completely incompatible cohabitants.
What water temperature and pH parameters do Pea Puffer and Swordtail need?
Both species require compatible parameters. Pea Puffer needs a temperature of 74°F to 82°F and a pH of 6.5 to 7.5. Meanwhile, Swordtail needs a temperature of 72°F to 79°F and a pH of 7.0 to 8.0. Shared overlap range: 74°F–79°F temperature and 7.0–7.5 pH overlap.
What is the minimum combined tank volume required to house Pea Puffer and Swordtail?
To successfully house both species together, a baseline of 20 gallons is required. However, because the setup includes territorial behavior from Pea Puffer (aggressive), we recommend an adjusted minimum tank volume of at least 40 gallons (adding a 20-gallon safety buffer) to establish separate visual boundaries and minimize stress.
